The Legal Framework of a Tax Appeal
A decision of a tax authority is not the final word: articles 299, 300, 302, 304 and 305 of the Tax Code regulate the full cycle of initiating a dispute, accepting a complaint for consideration, examining it and pursuing further appeal. Knowing these norms is decisive both for not missing the deadline and for avoiding a rejection of the complaint at the first stage over a formal defect. This page explains each stage, the deadlines and the mistakes that cost complainants most often.
The Right of Appeal and Its Deadlines
Under article 299, a person may appeal a decision of a tax authority within 30 days of its delivery. A tax audit act and the decision issued on its basis are appealed together with the tax demand issued on those documents. After the 30-day window, initiating a dispute remains admissible on the basis of newly discovered circumstances or evidence — facts the complainant did not and could not know, and whose timely submission would have produced a favourable decision. Where the decision was not sent to the complainant, the term runs from the day the decision became known to them; a missed deadline may still be justified by proving that the delay was caused by reasons independent of the complainant. Importantly, an appeal does not suspend the operation of the decision, while breach of the period for adopting the decision may be treated as a deemed refusal and appealed as such.
Acceptance of the Complaint for Consideration
Article 300 sets procedural requirements whose breach means the complaint is not accepted: the complainant's identification or personal number and contact details must be indicated; the essence of the request must be clear; a copy of the contested decision must be attached; pages must be numbered, the text legible, drawn up in the state language and signed; where a representative acts, a document confirming authority is required. When a defect is found, the complainant is notified in writing and given at least 5 days to cure it, though the dispute resolution body may accept the complaint despite the defect if it does not substantially hinder its examination. As a rule, the complaint is submitted electronically, its form being determined by a government regulation.
